Gigacatalyst Self-Serve Registration API
The one public, unauthenticated operation Gigacatalyst publishes on its own behalf. A coding agent reads the project's API surface, builds a JSON description of it (organization, integrations, tools with inputSchema and outputSchema, safety levels, optional domain documents) and POSTs it to https://v2.gigacatalyst.com/api/self-serve/register, which creates the human's workspace and returns a single-use sign-in URL, an account password, a tool count, and a per-connection credential checklist. The request and response contracts, the validation rules the endpoint enforces, and the auth vocabulary are documented in full in the provider-published agent instructions at https://v2.gigacatalyst.com/agent.md. Verified live: OPTIONS returns 204 with "allow: OPTIONS, POST"; GET returns 405.
